moon VS turborepo

(for context - I'm not interested in first class node support)

This seems pretty cool. I particularly like how 'gradual' it seems to be relative to things like Bazel, i.e. you can take some shell scripts and migrate things over. I did have a play and hit an initial problem around project caching I think, which I raised at [0].

One comment, from the paranoid point of view of someone who has built distributed caching build systems before is that your caching is very pessimistic! I understand why you hash outputs by default (as well as inputs), but I think that will massively reduce hit rate a lot of the time when it may not be necessary? I raised [1].

As an aside, I do wish build systems moved beyond the 'file-based' approach to inputs/outputs to something more abstract/extensible. For example, when creating docker images I'd prefer to define an extension that informs the build system of the docker image hash, rather than create marker files on disk (the same is true of initiating rebuilds on environment variable change, which I see moon has some limited support for). It just feels like language agnostic build systems saw the file-based nature of Make and said 'good enough for us' (honorable mention to Shake, which is an exception [2]).

There are many tools like Lerna, Nx, Turborepo, Moon, Rush, and Bazel, to name a few. Today, we'll be using Turborepo, as it's lightweight, flexible, and easy to use.

You should give moon a try: https://moonrepo.dev/

Turborepo: Smart build system for JavaScript/TypeScript monorepos

We’ve only scratched the surface of what we can do with Turborepo. You can find more examples in the Turborepo examples directory on GitHub. Skill Recordings on GitHub is also another great resource that has been around since Turborepo was first released.

git clone https://github.com/vercel/turborepo.git

I use https://turborepo.org/ to facilitate my monorepo. Essentially it's a way of structuring your configs, UI; apps etc and you consume each like an internal package. I find benefits for this as the kinds of sites I make will generally have an internal app, an admin panel and a marketing site. I can write UI, config etc in one place and consume them over the three projects to keep everything consistent.

The latest addition to the Composer Suite monorepo, Turborepo optimizes monorepo workflows by caching build artifacts. This may sound a little abstract and boring, but what this actually means is that when you build something within your monorepo, Turborepo will make sure only the things that it depends on are rebuilt; everything else will be retrieved from a cache that either lives on your local computer, or a remote cache server. Adding Turborepo to the Composer Suite monorepo pretty much halved CI build times, but it was also a way to teach Vercel, which I use for hosting the various example apps in the repo, to only actually deploy the ones that have changed since their last deployment. And that's really cool!

NB: "Turbo" also has other meanings in a React Native context, so don't confuse Hotwire Turbo Native with Turbo Modules or Turborepo (as used in create-t3-turbo, mentioned later here).

Personally I just use this: https://github.com/vercel/turborepo/tree/main/examples/with-tailwind

To set up our monorepo we will use Turborepo which will take care of installing the basic parameters for us.
